Approximate computing has emerged as a new paradigm for high-performance and energy-
efficient design of circuits and systems. For the many approximate arithmetic circuits …

As an important arithmetic module, the adder plays a key role in determining the speed and
power consumption of a digital signal processing (DSP) system. The demands of high speed …

Often as the most important arithmetic modules in a processor, adders, multipliers, and
dividers determine the performance and energy efficiency of many computing tasks. The …

In this brief, we propose a fast yet energy-efficient reconfigurable approximate carry look-
ahead adder (RAP-CLA). This adder has the ability of switching between the approximate …

In this brief, a low energy consumption block-based carry speculative approximate adder is
proposed. Its structure is based on partitioning the adder into some non-overlapped …

Approximate computing is a promising approach for low-power IC design and has recently
received considerable research attention. To accommodate dynamic levels of …

This paper presents an energy-efficient approximate adder with a novel hybrid error
reduction scheme to significantly improve the computation accuracy at the cost of extremely …

In this article, we present an energy-efficient approximate CGRA (X-CGRA). Instead of
conventional exact arithmetic units, it employs configurable approximate adders and …

The rapid growth of demanding applications in domains applying multimedia processing
and machine learning has marked a new era for edge and cloud computing. These …

Adders are key building blocks of many error-tolerant applications. Recently, a number of
approximate adders were proposed. Many of them are block-based approximate adders. For …
